MP4030GS LED Driver IC - Equivalent & Substitute Parts

Part Overview

The MP4030GS is an active AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc. This component is designed for lighting applications requiring triac dimming capability in a compact 8-SOIC surface mount package. The device operates across a 11V to 27V supply range and features a flyback topology without internal switching capability. As an active product with full RoHS3 compliance and established inventory availability, substitute parts are identified to provide design flexibility, alternative sourcing options, or specific application requirements where alternative electrical or mechanical characteristics are beneficial.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4030GS are qualified based on the following core substitution criteria:

Primary Compatibility Parameters:

• AC DC offline switcher topology for lighting applications
• Single output configuration
• Triac or PWM dimming capability
• Surface mount packaging
• RoHS3 compliance and active product status
• Operating temperature range suitable for -40°C to 125°C minimum

Substitution Logic: Three qualified substitute parts are identified. The HV9923N8-G and HVLED805TR maintain the same functional category (AC DC offline switcher LED driver) with compatible dimming methods. The LNK420EG extends the supply voltage range significantly while maintaining flyback topology and PWM dimming. All three substitutes are active products with full regulatory compliance. Differences in package type, internal switch configuration, and specific voltage/current ratings are noted to enable informed selection based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

HV9923N8-G (Microchip Technology): Select this substitute when triac dimming compatibility is required and the application supply voltage range extends to 400V. This part maintains triac dimming functionality identical to the MP4030GS. The higher maximum supply voltage accommodates wider input ranges. Note that the minimum supply voltage is 20V, which may require circuit redesign if the application requires operation below this threshold. Operating temperature maximum is 85°C, lower than the MP4030GS specification. RoHS3 compliance and active product status confirm regulatory alignment.

HVLED805TR (STMicroelectronics): Select this substitute when PWM dimming is acceptable and the application requires extended operating temperature capability to 150°C. The supply voltage range (11.5V to 23V) closely matches the MP4030GS, making this a direct functional replacement for thermal-demanding environments. The 16-SOIC package is larger than the 8-SOIC MP4030GS, requiring PCB layout modification. RoHS3 compliance and active status are confirmed. Internal switching capability is present, differing from the MP4030GS architecture.

LNK420EG (Power Integrations): Select this substitute when the application requires significantly higher supply voltage capability (36V to 725V) and higher output current (4.9A). This part operates at 66kHz frequency and features PWM dimming. The through-hole eSIP-7C package differs substantially from the MP4030GS surface mount configuration, requiring complete PCB redesign. Extended operating temperature to 150°C is supported. RoHS compliance and active product status are confirmed. This substitute is suitable for high-voltage lighting applications beyond the MP4030GS voltage range.

Frequently Asked Questions (FAQ)

Q: Can HV9923N8-G directly replace MP4030GS on the same PCB? A: No. While both support triac dimming and are AC DC offline switchers, the HV9923N8-G uses a TO-243AA package versus the 8-SOIC package of MP4030GS. PCB footprint modification is required. Additionally, the minimum supply voltage is 20V compared to 11V for the MP4030GS.

Q: What is the key difference between triac and PWM dimming options? A: The MP4030GS uses triac dimming, which is compatible with standard wall dimmer switches. The HVLED805TR and LNK420EG use PWM dimming, which requires PWM-compatible control circuitry. These are not interchangeable without circuit redesign.

Q: Is the LNK420EG suitable for low-voltage applications? A: No. The LNK420EG minimum supply voltage is 36V, significantly higher than the MP4030GS (11V minimum). This part is designed for high-voltage lighting applications and is not suitable for low-voltage designs.

Q: Can I use HVLED805TR as a drop-in replacement? A: No. The HVLED805TR uses a 16-SOIC package compared to the 8-SOIC package of MP4030GS. PCB layout modification is required. Additionally, it uses PWM dimming instead of triac dimming, requiring control circuit changes.

Q: Are all substitute parts RoHS3 compliant? A: HV9923N8-G and HVLED805TR are RoHS3 compliant. LNK420EG is RoHS compliant. All three meet regulatory requirements for the specified applications.

Q: What is the operating temperature consideration for substitute selection? A: MP4030GS operates to 125°C (TJ). HV9923N8-G operates to 85°C (TA), which is lower. HVLED805TR and LNK420EG both operate to 150°C (TJ), providing extended thermal capability for demanding environments.

Q: Do all substitutes have the same number of outputs? A: Yes. All substitute parts (HV9923N8-G, HVLED805TR, LNK420EG) feature single output configuration, matching the MP4030GS specification.
